Hi @maliming,
Thanks. So should we downgrade framework to lower version or using another library like devart?

https://github.com/oracle/dotnet-db-samples/issues/81#issuecomment-728258466 we're still on track for a December/January Oracle EF Core 5 release.
https://www.nuget.org/packages/Devart.Data.Oracle.EFCore is supported net 5.0 but it not free library.
You can wait for
Oracleor tryDevart, otherwise you can only use net core 3.x. -

Hi maliming,
I am trying to install abp suite version 3.3.2 to downgrade framework to net core 3.1. Can you help me fixing this error:

Package Volo.Abp.Suite 4.0.0 supports: net5.0 (.NETCoreApp,Version=v5.0) / any The tool package could not be restored. Tool 'volo.abp.suite' failed to install. This failure may have been caused by:
- You are attempting to install a preview release and did not use the --version option to specify the version.
- A package by this name was found, but it was not a .NET Core tool.
- The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
- You mistyped the name of the tool.
For more reasons, including package naming enforcement, visit https://aka.ms/failure-installing-tool [10:05:13 INF] You can also run the following command to install ABP Suite. [10:05:13 INF] dotnet tool install -g Volo.Abp.Suite
